Abstract
In the present invention, there are provided a movement member which includes an engaging section, which is engaged with an intermediate part of an operation shaft of a joystick device, and operates as one body with the operation shaft at a time of performing an inclining operation of the operation shaft, and a damper case in which the movement member is movably inserted, and which holds a viscous fluid which increases a sliding resistance of the movement member when the movement member is moved. Thereby, a desired operational sensation can be always obtained, and a stable bending operation can be performed.
